[jira] Created: (AMQ-2740) NullPointerException in Web Console when
using an existing browser session with a restarted broker instance
NullPointerException in Web Console when using an existing browser session with a restarted broker instance
-----------------------------------------------------------------------------------------------------------
Key: AMQ-2740
URL: https://issues.apache.org/activemq/browse/AMQ-2740
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.3.2
Environment: Windows
Reporter: Adrian Trenaman
As per summary above. If you have a browser open to the web console, and create a queue it works OK. However, if you then restart the broker adn then try and perform an action like deleting the queue (from the web console) then you'll see the NPE in the broker's log.

I think this has something to do with stale session secrets, and is a consequence of support that was put in to protect ActiveMQ against CSRF (cross-site request forgery) attacks. The original CSRF error was alarming; this error, however, is a plain old NPE and we should fix it.

[jira] Commented: (AMQ-2740) NullPointerException in Web Console
when using an existing browser session with a restarted broker instance
Posted by "Adrian Trenaman (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/activemq/browse/AMQ-2740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=59442#action_59442 ]
Adrian Trenaman commented on AMQ-2740:
--------------------------------------
Just another note on this - if you explicitly refresh the browser page before you do a delete, then the error goes away. This supports my suspicion about this being down to stale session information.
